Reaction Conditions

Reaction Steps

To a solution, heated at 80° C. for 2 hours, of 6-benzoyl-benzothiazolinone (6.7 mmol) in the presence of K2CO3 in 20 ml of DMF there is added ethyl 2-[4-(2-chloroethoxy)phenoxy]-2-methylpropanoate. The reaction mixture is heated at 120° C. for 5 days, cooled, hydrolysed using 100 ml of water and rendered alkaline using 1N NaOH. The precipitate obtained is filtered off and then recrystallised from cyclohexane to yield the title compound in the form of a white powder.
